新建redis.properties

## crud ##

新建dao层crud方法，此处引用的是个人封装好的增删改查方法，在不粘贴。

@Repository(value = "redisRepository")
    public class RedisRepository extends AbstractSpringRedisCacheEnhance { 
    
        @Autowired
        RedisTemplate<String, Object> redisTemplate;
    
        @Override
        public StringRedisTemplate getStringRedisTemplate() {
            return null;
        }
    
        @Override
        public RedisTemplate<String, Object> getRedisTemplate() {
            return redisTemplate;
        }
    }

# 总结 #

按照以上操作即可完成spring集成redis哨兵模式，简单而简洁。哨兵模式对于服务器防灾上有很好的可用性，保证服务

健壮可用，方式因服务器故障导致网站缓存穿透而致网站运行不畅。是单例redis基础之上的一个升级方案。
